- F4100 provides a common development platform. The platform consists of the following five parts:
1. F4100 controller board;
2. DMD motherboard, DMD chip, and cable;
3. Upper computer control software F4100 and D4100;
4. Power cable;
5. Experimental power supply, 5V @ 5A type.
The F4100 system provides complete interfaces (USB or extension interfaces), data processing (Virtex 5, DDR), and DMD controllers (DDC4100, DAD2000, DMD) in DLP development and application. The following diagram is a simplified schematic diagram of the F4100 control platform:
The F4100 system includes:
1. Power-on and reset driver for two DAD2000: Realize reset control for 16 blocks of DMD mirror surface, while supporting higher frequency reset. Single DAD2000 operates in XGA mode, and two DAD2000 operates in 1080P mode;
2. DDC4100 digital controller: The FPGA XC5VLX30 chip from Xilinx Company is used to achieve complex control of DMD and DAD2000, providing high-speed 32bit/64bit low voltage differential signal (LVDS) data and control user interfaces. Its interfaces are all from the user FPGA, and initialization and control of DMD and DAD2000 are realized based on the input signals from the user FPGA. The DDC4100 digital controller is actually an encrypted chip;
3. 32bit/64bit, 400MHz double data rate (DDR) DDC410;
Data interface: 32-bit XGA interface operation; 1080p operation of a 64 bit interface;
4. 5V power input connector: on-board voltage regulator and other power supplies;
5. Large capacity user FPGA: FPGA XC5VLX50-1ff1153 for Xilinx company, for users to complete interface design and data processing;
6. A 64 bit DDR2 SODIMM connector: ultimately developing image storage for users;
7. Onboard Cypress 68013A USB controller: ultimately developing USB interfaces for users;
8. Output expansion connector: Connect to a standard compatible motherboard product. The board level design includes LVDS twisted pair design, supporting 64 bit LVDS connection to the expansion connector to achieve customer interface;
9. Flash memory: developing non volatile storage for end users;
10. Different I/O connectors: including a logic analyzer connected to the Micor test connector, JTAG simulation head for device programming, and GPIO universal digital IO interface.
